The present invention relates to a mobile communication device having a keyboard and a method for controlling the operation of the keyboard of such a mobile communication device. The keyboard provides a QWERTY styled layout including a keypad similar to a ITU-T keypad. Applications executed on the mobile communication device are adapted to switch an operation mode of the keyboard such that in accordance with a certain expected information input, different assignments of the keys of the keyboard are active. The keyboard operation modes improve the usability of the keyboard and allow the number of total keys for operating the mobile communication device to be reduced resulting in lowered cost of manufacture.

Mobile communication device having a keyboard including a keypad

A method of transferring a data packet from a providing communication terminal to a requesting communication terminal, wherein the requesting communication terminal transfers a message to the providing communication terminal including a requests for receiving the data packet and a first unique identification code identifying the requesting communication terminal. Upon receipt of the message the providing communication terminal verifies the validity of the first unique Identification code. When the verification has been ended successfully, the providing communication terminal responds by transferring a message to the requesting communication terminal including the requested data packet and a second unique identification code, Then the requesting communication terminal verifies the validity of the second unique identification code and stores the data packet accordingly when the verification has been successful.

Data transfer verification based on unique ID codes

A communications device according to the invention comprises a telephone set (7), which has a first control device (9) and a main data memory (8) for storing first data, and at least one data input unit (1) which can be connected to the telephone set (7) and has a second control device (3) and an auxiliary data memory (2) for storing second data which represent a part of the first data and via which the first data can be accessed. Both control devices (9, 3) are designed such that, in the event of a data change in one of the data memories, they allow a corresponding change to be made to the data assigned to them in the other data memory.

Communications device

The present invention relates to a telephone which has, on account of its many functions, a multistage menu structure for operator prompting. In order that a user does not have to remember the entire menu, or the point where he is in the menu at a given time if he pauses when operating the unit, there is specified a process for communication between the telephone and the user which, by means of a program, indicates to the user when he inputs a help signal a program branch previously selected by him and the next options available to him within this program branch. Furthermore, a voice dialling system for carrying out such a process is specified.
